Chapter 16, Problem 13TYU
Summary Introduction
To discuss: How the TAL protein’s structure suggests its functions on the basis of its interaction with DNA.
Concept introduction:
TAL proteins are found in Xanthomonas bacterium. It stands for transcription activator–like (TAL) effector proteins. These are secreted when the bacteria infect certain plant species such as rice, citrus fruits, cotton, and tomatoes. TAL effector proteins contain DNA-binding region through which they enter the plant nucleus and activate transcription leading to infection in the plant.

Question 3
List three characteristics of the structure of the DNA molecule.
Question 4
Suppose you have a 5'-AGAGTGCGTA-3' sequence on one strand of the DNA. What is the base sequence that should appear on the other complementary strand of the DNA?
Please ASAP. Thank you.
Regarding the double helix of DNA, which of the following is true?
a.
Guanine pairs up with cytosine with three hydrogen bonds
b.
Complementary strands of DNA are held together by covalent bonds
c.
The backbone consists of ribose sugars H-bonded to phosphate groups
d.
Uracil pairs up with adenine with two hydrogen bonds
why is recombinant DNA is possible becuase we know dna molecules from all organisms share the same chemical structure and differ only in the nucleotide seqeunce within the identical structure

- VISUALIZE Sketch a pyrimidine nucleotide subunit that would be found only in RNA. Circle and label the three components that make up this type of nucleotide. Explain what changes in the functional groups of this subunit would have to occur for it to be found in a DNA molecule.arrow_forwardUsing Figures 8.7 and 8.9 as a guide, draw a dinucleotide composed of C and A. Next to this, draw the complementary dinucleotide in an antiparallel fashion. Connect the dinucleotides with the appropriate hydrogen bonds. FIGURE 8.9 The two polynucleotide chains in DNA run in opposite directions. The left strand runs 5 to 3, and the right strand runs 3 to 5. The base sequences in each strand are complementary. An A in one strand pairs with a T in the other strand, and a C in one strand is paired with a G in the opposite strand. FIGURE 8.7 Nucleotides can be joined together to form chains caled polynucleotides. Polynucleotides are polar molecules with a 5 end (at the phosphate group) and a 3 end (at the sugar group). An RNA polynucleotide is shown at the left, and a DNA polynucleotide is shown at the right.arrow_forwardThese highly polymorphic molecular markers are useful in DNA fingerprinting: (a) plasmid vectors (b) cloned DNA sequences (c) palindromic DNA sequences (d) short tandem repeats (e) complementary DNAsarrow_forward
- Need help 1) Say you have an organism with a genome of 1 thousand bases (103) and a forward primer made up of 5 nucleotides (aka, a 5-mer) a)How many possible 5-mers are there? Remember that each position in the 5-mer has one of four nucleotides. b) Pick a 5-nucleotide position at random in the genome: what’s the probability that your forward primer matches there? Focus for now just on one strand of DNA. c) Pick a random 5-nucleotide position in the genome: what’s the probability that your forward primer does NOT match there? Focus for now just on one strand of DNA. d) How many physical locations might your forward primer sit in the genome? Focus just on one strand of DNA. Ignore whether or not it matches at a given location. this is one question with different parts. I would really appreciate it if all parts are answered. and I will defiantly rate.arrow_forwardThis image shows DNA (gray) interacting with a computergenerated model of a TAL protein (multicolored), one of afamily of proteins found only in a species of the bacteriumXanthomonas.
